Here is a short movie I made, on how to enabled "Distributed Builds" functionality on Xcode 3.x (Leopard). You _DO NOT_ need 10.5.x *server* to use this feature!. For those unaware of what this is; "Distributed Builds" basically spreads the workload of compiling your Xcode projects, across multiple Macs, so that the workload, and hence compilation time, can be reduced. There is a lot of FUD about this feature, I have found, and a lot of people are under the impression that you need a Leopard SERVER licence - you DON'T need it installed whatsoever.
